First thing I might do is make the bass drum (kick) a little louder/stronger. Also, for your snare rolls, I would make it crescendo. I also wouldn't make the end louder than the beginning. I would recommend that you change the bells to some short echo synth sample, as to keep the energy pushing to the end. Overall balance could use some work. You also want to make sure the melodic instruments are loud enough so people can easily distinguish it from everything else. Besides all that, it's an O.K. song. A bit repetitive though.
